Upgrading 1x8 pin GPU to a 1x8, 1x6 pin GPU

Ok so I'm not extremely Tech savvy and a newb at PC gaming/building. I'm Upgrading my MSI Gtx 1070 Aero OC which has a 1x8 pin slot to a new RTX 2070 which has a 1x6, 1x8 pin, I have no idea how to go about this, I saw something about the gpu will come with a molex adapter to 6 pin, but from what I can see there are like 3 molex ports coming from my PSU one white and 2 black, Idk which one to use, Oh and btw my PSU is a corsair cx650m

You don't need adapters your PSU has enough connections to power a 2070:

1 x 20+4-Pin Motherboard cable
1 x 4+4-Pin, works as either 4 or 8-Pin CPU power Cable
2 x 6+2-Pin PCIe
4 x 4-Pin peripheral
6 x SATA cable
1 x Floppy power
